Subject: [PATCH] When disabling SSE,  make sure -fpmath is not set to use SSE
 either

This fixes errors when we inject sse options through CFLAGS and now
that we have -Werror turned on by default this warning turns to become
error on x86

gcc -m32 -march=core2 -mtune=core2 -msse3 -mfpmath=sse -x c /dev/null -S
-mno-sse -mno-mmx

generates warning
/dev/null:1:0: warning: SSE instruction set disabled, using 387
arithmetics

where as

gcc -m32 -march=core2 -mtune=core2 -msse3 -mfpmath=sse -x c /dev/null -S
-mno-sse -mno-mmx -mfpmath=387

Generates no warnings
